Abgent has over fifteen years of experience producing recombinant proteins in E. coli and mammalian cells (CHO and HEK293, etc), and we have added a powerful yeast expression platform to our menu of services. With state-of–the art molecular biology and protein biochemistry labs, we work with our clients to rapidly evaluate in parallel to identify the optimal expression system for candidate proteins.

Certify that your antibodies work, while saving time and money. Abgent’s experienced staff custom validates more than 1,000 antibodies each month in Western Blot (WB), Immunofluorescence (IF), Immunohistochemistry (IHC), Flow Cytometry (FC) and additional applications. Proper validation with controls and optimization ensure the quality of the antibody, and establish confidence in your results.

Thousands of laboratories across the world have published research that depended on the performance of biological reagents manufactured by Abgent to advance their research. Check out links to articles that cite our custom service antibodies, peptides, and proteins in major peer-reviewed journals, organized by research category.

18,000+ products cover the ten top research categories, including cancer, metabolism, cardiovascular, neuroscience, and stem cells. Each antibody is crafted with care according to rigorous protocols for immunogen design and preparation, presentation to host animal, and high-affinity purification against the antigen. Quality is embedded in the production process to assure the best antibody for you.

Abgent develops 1000+ new products per year. We provide tools for path-breaking research by developing antibodies that detect a comprehensive library of novel and established targets. For established targets we seek to add antibodies that recognize new epitopes, including post-translational modifications such as phosphorylation and methylation. For new targets we consult with leading experts to accelerate development of antibodies that will propel state-of-the-art research in cellular health and disease.

Abgent offers custom and catalog peptides to pharmaceutical, biotechnology companies and academic institutions worldwide. All peptides are manufactured in the United States to exacting standards in support of U.S. and international clientele. Custom peptide services include long peptides (>100mer), cyclic peptides, difficult sequences, fluorescent labels, and phosphopeptides.

The majority of Abgent antibodies are produced using peptide immunogens. These immunospecific peptides can be used as blocking agents when using the complementary antibodies in a range of applications.

Researchers worldwide depend on Abgent FLcDNA clones to accelerate their research. Expression-ready clones are convenient solution that decreases the time required to start an experiment and increases the chances of success.

The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.

The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

Autophagy

Autophagy is a cellular degradation process that involves the delivery of cytoplasmic cargo to the lysosome. Autophagy occurs at low basal levels in all cells to maintain homeostatic functions such as protein and organelle turnover. It is rapidly upregulated when cells need to generate intracellular nutrients and energy during starvation, growth factor withdrawal, or high bioenergetic demands. Autophagy is also important process to dispose of damaging cytoplasmic components during oxidative stress, infection or protein aggregate accumulation. Consequently, impairment in autophagy can lead to development of certain pathological conditions1,2.

It is well established today that organization of misfolded proteins in aberrant structures such as oligomers initiates profound cellular dysfunction and eventually can result in development of neurodegenerative diseases. Alzheimer’s and Parkinson’s diseases exemplify the contribution of aggregate-prone proteins to disease pathophysiology3.

Eukaryotic cells coordinate protein-folding reactions both in the cytosol and in the ER. Differential protein synthesis rates and protein folding accuracy are part of separate signal transduction pathways triggered by the ‘unfolded protein response’ (UPR) in the ER. A subset of soluble molecular chaperones modulates protein folding in the cytosol. Misfolded proteins can be retained associated with molecular chaperones within the ER lumen or translocated to the cytosol for ER-associated degradation (ERAD) through the 26S proteasome or through autophagy. Autophagy is activated in response to this blockage of the proteasome by the pathogenic proteins. However, overloading of the autophagic system can occur and lead to cell death. Autophagic degradation is utilized to reduce ER stress resulting from protein misfolding cluttering.

The discovered activation of autophagy in response to ER stress and cytosolic accumulation of protein aggregates in brain raises implications for understanding and tackling neurodegenerative protein misfolding diseases4. Effects of autophagy on aggregate-prone proteins in other tissues may result in other medical conditions such as myopathy.

Moreover, autophagy plays a role in cancer development: it acts as a tumor suppressor by removing damaged organelles and reducing genome instability, while in other conditions this process helps cancer cells to survive under low nutrient conditions or in cancer treatment.

Innate and adaptive immunity are also dependent on autophagy process. Bacteria, viruses and protozoans are generally removed from host cells by autophagy mechanism. Autophagy also may help to prevent inflammation and autoimmune diseases.
